PUMP POWER.

Specification of Letters Patent.

Patented July 9, 1907.

Application filed October 31, 1906. Serial No. 341,429.

of Blackford and State of Indiana, have invented newl and useful Improvements in Pump Power, of which the following is a specification.

This invention is a power mechanism particularly adapted for operating oil well and other pumps.

The object of the invention is -to provide a band wheel power having several motions, as compared to the ordinary power having only a single motion.

A further object of the invention is to provide improved means for lubricating the bearing parts or surfaces of the power, so as to avoid friction, wear and noise.

The power herein disclosed has two different motions transmitted from one motion of the band wheel. This is advantageous in the practical operation of such devices in oil fields, because wells are of different kinds and can be operated by different strokes. Thus in a lield having several large salt-water wells and other head wells, the latter can usually be pumped off in three or four hours, whereas the formerV would require twelve hours or more.' With this power the salt wells could be connected to the double or frequent motion wheel and the head wells to the single motion, thereby decreasing :the time the power would have to operate, and avoiding the use of separate gas or steam engines for pumping the salt wells. The power has the further advantage that the bearings are all very large, making it almost impossible to wear out, andthe power sets very close to the ground and no over braces ortimbers are necessary.

Other advantages of construction will be apparent from the following description and the accompanying drawings.

In the drawings, Figure l is a vertical central section of the power. Fig. 2 is a top plan view thereof. Fig. 3 is a section on the line 3 3 of Fig. l. Fig. 4 is a top plan view of the sliding block shown in Fig. 3. Fig. 5 is a top plan view of one of the sliding blocks of the trammel gear.

In the drawings, 6 indicate a pair of parallel longitudinal sills and 7 a pair of cross sills secured thereto in any suitable manner. The working parts of the apparatus are supportedv mainly upon the `cross sills 7. The bed plate or casting 8 rests upon and is bolted to the sills and has at the center an annular well or groove formed by inner and outer circular walls 9 and l0, cast integral with the bed plate. The inner wall ofthe groove is preferably tapered or frusto-conical, as shown, and provided with a top part or plate 1l over the central recess.

Mounted upon the bed plate is the central or hub casting l2 of the belt wheel. This casting has a raised part or crown I2 at the center, within which is a depending tapered rib 13 which fits within the groove in the bed f plate. Bearing balls 14 are placed between the lower edge of the rib and the bottom of the groove, and the upwardly projecting edge of the circular wall l0 projects into the annular space between the rib and the sides of the crown. From the crown the hub plate or casting extends outwardly and horizontally, and is bolted to the arm 15 to which the rim 16 of the main horizontal belt wheel is attached. This construction. gives a very wide bearing between the bed plate and the hub plate. Furthermore, the parts are connected by a central bolt 17 which serves to prevent lift of the upper plate. This bolt has a cup head located in a recess 1S on the under side of a trammel plate 19 to be hereinafter desscribed.

The hub plate l2 has formed on the upper surface thereof an eccentric groove 19 within which lits the rib 20 en the under side of the eccentric ring 21. The ring is held down in place by clips 22, and is provided with a plurality of holes around the edge at which may be attached a plurality of well connections 23, the number of these being varied according to the number of wells to be operated. The eccentric gives the normal motion or stroke. It is obvious that at each revolution of the belt wheel the eccentric will be actuated accordingly.

To produce a double or faster stroke I provide a trammel gear which is also operated by the belt wheel. This trammel gear consists of a trammel plate 19 having dove-tailed grooves 24 at a right angle. The plate is bolted as at 25 to the crown of the hub casting, and rotates therewith. The blocks 26 slide in the groove, and these blocks have, in the bottoms thereof, oil recesses 27. Each block also has, at the top, a circular rib 28 which fits in an annular groove 29 formed in the under side of the upper trainmel disk or plate 30, and

receive nuts 32 to hold the upper plate to the blocks. The bolts pass through undercut recesses 33. per plate 30 is provided around its edges with a series of connections 34 for attachment of the ropes which extend to the wells. A connecting rod 35 extends from one end of the trammel disk 3() to connection with a pivot block 36 which turns in an under-cut recess 37 in a bearing piece 38 which is slidable in a guide-way 39 in the top of a standard 40 mounted on the mud sills 6. The connecting rod 35 is extended for connection to a power pump arm, as indicated at 4l. The wrist pin or bolt 42, which connects the rod to the block 36, in connection with the slide, permit and guide the mov ement of the parts incident to the operation of the trammel gear.

All the bearings described will be found to run in oil. Thus the groove in which the rib 13 fits is filled with oil, likewise the eccentric groove 19a and the wrist block groove 39. The trammel blocks 26 form cups at the top which may be filled with oil, and oil is placed and held the blocks are also formed with central bolts 31 which- The up- Within the trammel grooves 24. All the cntacting movable parts are thereby thoroughly lubricated and an easy and noiseless action is assured'. Two different movements are obtained Without the use of toothed gears, the single movement being available from the eccentric and the double movement from the trammel gear. Therefore the Well connections may be attached to either, according to the nature o the Well to be pumped.y Power is applied to the belt Well from the engine provided, in the customary manner.

I claim:

1. In a power mechanism, the combination of a frame, a base plate mounted thereon and having an annular groove the walls of which project above the plate, a belt wheel having a raised crown into which the upper ends of said walls extend and a rib extending downwardly from the top of the crown into the groove, and motion-converting devices operatively connected to the Wheel.

2. In a power mechanism, in combination, a belt wheel having a raised crown at the center and a dropped body around the same, and ring flanges projecting upwardly from said body around said crown, motion-converting devices mounted on the crown and extending outwardly' therefrom over the body, and an eccentric ring located-be tween the body and said outwardly extending devices and engaging the anges.

3. In a power mechanism, in combination, a belt Wheel, a tramrnel gear mounted thereon comprising a lower plate secured to the Wheel and having crossed slots, blocks slidable in said slots and having raised circular rims, and an 'upper plate secured to the blocks and having circular grooves on its under side, into which the rims extend, and also having a connecting rod extending outwardly from the upper plate, and a guide for the outer end of the rod.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
